This paper presents an experimental investigation into the effects of freeze-thaw cycling on the FRP-concrete interfacial bond behavior. The strain distributions in the concrete and FRP are determined using the displacements obtained from an optical technique based on digital image correlation (DIC). The influence of freeze-thaw on stress transfer during fracture is studied. The results of the strain analysis are used to establish the non-linear material law for shear fracture along the FRP-concrete interface for specimens subjected to freeze-thaw cycles. The results show that freeze-thaw cycling produces significant decrease in the ultimate load transferring capacity and the interfacial fracture energy. [ABSTRACT FROM AUTHOR] |
